Filed: 1973-07-21
Abstract: 1478121 Radiography EMI Ltd 4 July 1974 [21 July 1973] 34859/73 Heading H4F A radiographic apparatus comprises a source 9 of X or gamma radiation arranged to produce a sectoral swath 10 of radiation passing through a body to be examined held within a flexible hose 1 forming part of a water-filled reservoir 2, the emergent radiation being divided into a set of spaced beams by collimators 15 each containing a scintillator 14 connected by a flexible lightguide 17 to a photomultiplier 18 providing a beam signal for processing, the source 9, collimators 15 and the detecting system 14, 17, 18 being rotatable about the object on a turntable 13 driven by a motor 11 and the collimators 15 being reciprocable in direction 24A relative to the source 9 by a motor 26 and a crank 24 so as to bring the passages of the collimators 15 into positions previously occupied by the walls of the collimators, thereby obtaining beam transmission information which would otherwise be lost. The reciprocation of the collimators 15 can take place continuously during rotation of turntable 13 or at 180 or 360 degree steps. The scintillators 14 and photomultipliers 18 may be reciprocated with the collimators or may be stationary if they are sufficiently large to cover the movement of the collimators. A shutter may be provided between the source 9 and the body to define the incident radiation as a set of beams, this shutter being moved in synchronism with the collimators.

A machine for cleaning the interior surfaces of drums and other hollow cylindrical and tubular articles by blasting with shot or other abrasive blasting material comprises a rotating table, on which the articles are loaded with their axes vertical, which is moved intermittently to bring the articles one at a time to the position where the blasting is to take place, means for lifting the article vertically at this position through the operative zone of a blastant throwing wheel, the distance which the article is lifted being such that its full length is subjected to the blasting, and means for reversing the movement of the article so that it is lowered again to the table through the operative zone of the throwing wheel, the intermittent rotary movement of the table being automatically controlled, interlocked and registered by electrical or other means to bring each article to the blasting station, correctly position it and  retain it there for the necessary time for the blasting operation. A machine comprises a horizontal table A having four locating means a, each adapted to receive a cylinder B. The table is intermittently rotated, e.g. by an electric motor, through 90 degrees so as to bring a cylinder into a blasting chamber C in which is a throwing wheel D. A fork E engageable with the bottom edge of the cylinder is secured to a slide e affixed to an endless chain or cable E<SP>1</SP> passing over pulleys e<SP>1</SP>, e<SP>1</SP>, one of which is motor driven. The throwing wheel D is secured to a vertical  hollow shaft F rotated by a pulley f. A shot feed tube F<SP>1</SP> passes through the shaft F and is secured at its upper end to the machine; it may be rotated. The shot is fed by gravity or by pressure, such as compressed air, screw conveyer or vibratory methods. At the centre of the bottom plate d of the wheel is fitted a removable plug G to ensure even distribution of the shot over the blades d<SP>1</SP>. The plug may be flat, conical, convex or concave; it may be of the two-tier or cascade type, shot being fed to the centre of the plug G and delivered through apertures g therein. The machine may also include means for simultaneously cleaning the lids or tops and bottoms of cylinders which are to be supplied therewith.

A bus-bar protective arrangement has a resistor 11, 12 or 13 connected to each current transformer 8, 9 or 10 to supply a potential to an input of an " AND " element 14, and a resistor 15 is connected in a summation circuit to all the current transformers to supply a potential to a further input of the " AND " element. Under normal conditions, the currents sum to zero so that no potential is applied to the input of the " AND " element connected to the resistor 15 and the " AND " element provides no output signal. In the event of a bus-bar fault, the currents no longer sum to zero and potentials are present at all the inputs to the " AND " element 14 which provides an output to energize a relay 16. The relay 16 closes contacts to produce tripping of circuit-breakers 5 ... 7.

Title: A control device for sheet feeding apparatus
IPC: B65H3/10
Filed: 1937-12-24
Abstract: 497,885. Feeding sheets. SPIESS. G. Dec. 24, 1937, No. 35821. Convention date, Dec. 24, 1936. [Class 100 (i)] In a sheet-feeding apparatus in which the sheets are separated from a fanned-out pile and forwarded to a machine by a continuously rotating suction roller 5, the separated sheets are timed accurately to correspond with the working of the machine by employing sheet-controlling tongues 30 which arrest the separated sheet temporarily before it is engaged by the roller 5, the members 30 finally permitting the sheet to be forwarded by the roller 5 at a time in the working cycle of the machine which is under the control of a cam 16. The cam 16 is driven by a variable drive such as cones 11 and an adjustable belt 12, or by an electric motor with variable resistances, so that the feed can be adjusted for sheets of different sizes. The tongues 30 are mounted on an oscillating lever 29 connected by a link to a spring-controlled lever 27 actuated by the cam 16, and the tongues are received in grooves 33 in the cylinder 5 when the sheet is to be forwarded by the suction apertures 9 in the roller 5. These apertures are associated with a stationary suction nozzle 8, the air pressure in, which is controlled by a rotary plug cock 20 which is oscillated by a cam 15 on the shaft 14, and connects the nozzle 8 to atmosphere once for each rotation of the shaft 14. When the top sheet 31 is arrested by the tongues 30, air from a blast nozzle 4 is directed between it and the pile. A stripper 6 detaches the sheets from the roller 5.

Title: Improvements in or relating to automobile torpedoes
IPC: F42B19/40
Filed: 1920-12-24
Abstract: 171,323. Whitehead Torpedo Works, (Weymouth), Ltd., Sodeau, W. H., and Francombe, V. P. Dec. 24, 1920. Torpedoes, locomotive. - Relates to practice heads provided with a device for converting negative buoyancy into positive buoyancy to make the torpedo rise to the surface at the end of a trial run so that it may be recovered. According to the invention, the device is made so that it acts only when two conditions are satisfied, namely, when the torpedo is below a given depth and its speed has fallen below a predetermined value. As shown in Fig. 1, the practice head A contains water ballast which is intended to be expelled, by compressed air from a reservoir A<1> when a valve A<2> sealed with oil a<1> is opened. This valve is worked through a lever B<4> by a lever B<3> fulcrumed at b<3> on the rod C<x> of an hydrostat C and provided with a pawl B<2> for engagement with a rack b<2> on the rod b of a spring- controlled plate B when this is subjected to water pressure in proportion to the speed of the torpedo. If the torpedo should dive or come to the surface while running, neither the hydrostat nor the pressure-plate will separately open the valve A<2>; but when the speed falls at the end of a run when the torpedo is below a given depth, the pressure-plate is moved forward by its spring and the hydrostat compressed, and the combined effect of this on the lever B<3> is then sufficient to cause the intermediate lever B' to open the valve A<2>. Modifications of the manner in which the pressure-plate and hydrostat are constructed and interconnected are described. The buoyancy conversion may be performed by the dropping of solid ballast or the extension of a telescopic head instead of by the expulsion of water ballast. A clookwork or a salammoniac or like soluble plug may be added to cause the operation after a given time if the above-described mechanism has failed to act.
